Building Distributed GraphQL APIs

on YouTube ↗01h 05m

" summary

Shows a .NET demo using Hot Chocolate, Banana Cake Pop and Fusion to replace a monolithic GraphQL gateway with independently deployed subgraphs, composing schemas at build time and emitting query plans that reveal resolver steps. Demonstrates batching to turn N per-item subrequests into two optimized calls, working subscriptions across subgraphs via GraphQL over WS, and hot-reload Gateway configs. Claims developer scale benefits and cites a customer drop from 120 Apollo pods to 30 Fusion pods while keeping single-endpoint GraphQL for clients.
